The heat sink is a passive cooling component that dissipates heat from electronic parts in boiler and burner systems. By drawing thermal energy away from power transistors or control boards, it prevents overheating and ensures long-term reliability. This spare part is often used in conjunction with other heating equipment components to maintain safe operating temperatures. For technicians performing boiler maintenance, a properly functioning heat sink is crucial for system stability.
